Now that we've completed our pH tests on various sites throughout Greentown, we're seeing that some sites' pH results don't quite look the same. How is it that one location, which may be far away from another site, be a possible polluter?
Mrs. Brinza set up a demonstration to show how liquid pollution responds to a rain storm. Using blue food coloring as a model for pollution, she placed some food coloring on top of the sand to mimic someone dumping harmful chemicals into the ground. With a water bottle "rain storm" about to come, fourth graders gathered evidence for what can happen to pollution underground. Check out the pictures below to show how pollution can spread.
